Definitions

  • This invention relates to hydrant servicer carts, used in the refuelling of aircraft from pressurised underground mains accessed by hydrants at the loading/unloading aprons of airports.
  • the invention seeks to meet the need for a servicer cart which can remain on the apron at a particular bay while being readily movable from one side of the aircraft to the other, and is capable of servicing the full range of aircraft which may use the bay at which it is stationed.
  • Carts according to the preferred embodiment of the invention meet these requirements, while being readily manoeuvred by a single operator, typically having self-propulsion for ordinary operating needs and being towable for maintenance.
  • EP-A-0394543 discloses a hydrant servicer cart having a refuelling platform and a fuel conveying boom, both mounted to a chassis, and arranged for raising and lowering together.
  • an aircraft refuelling cart including:
  • the refuelling platform is mounted to the chassis by means of one or more scissor-action mechanisms, each including a plurality of pivotally interconnected support members.
  • the platform includes hand rails which are pivotally collapsible.
  • the boom is partly supported by the platform.
  • An embodiment of the invention to be described herein presents a small footprint but is capable of refuelling the full range of high-wing aircraft currently in use at major airports.
  • the cart illustrated in Figs 1 - 4 includes a chassis 10 carried on rear wheels 11 and front wheels 12, the latter being mounted on a turntable 13 enabling steering, and is provided with a retractable drawbar 37 engaged with the turntable 13.
  • hydrant hose 14 removably supported around the periphery of the cart
  • hydrant coupler 15 an inlet valve 16
  • surge suppressor 17 filter 18
  • fuel meter 36 A diesel engine 19 is fitted with a hydraulic pump to provide power to hydraulic motors (not shown) at both of the rear cart wheels, preferably both rear wheels, enabling the vehicle to be self-propelled, and to provide fluid to the rams controlling the raising and lowering of the refuelling platform 20.
  • the engine 19 also operates an air compressor 21 for operation of the hydrant valve, although this may be substituted by a product-driven compressor.
  • the refuelling platform 20 is raised and lowered by means of a scissors mechanism 22.
  • handrails 23 are pivotally collapsible as shown in Fig. 5 in relation to the embodiment to be described below.
  • Fig. 4 the rails are shown fully collapsed. This enables the cart to be used for servicing aircraft having the greatest wing height currently in use or planned, while being able to be contracted to an overall height of approximately 132cm.
  • fuel to the platform 20 is carried by a boom 24 consisting of lengths of rigid pipe coupled by pivoting couplings 25, the boom being supported by the platform 20.
  • the folding boom thus created is mounted athwart the cart to hinge in the same direction as the scissor mechanism 22, contributing to the compactness of the design.
  • fuel hoses 26 are coupled at 27 to the upper pivoting coupling 25, while the lower coupling 15 is fed from a platform hose valve 28 connected with the meter 18. Access to the platform is obtained by means of rear steps 31.
  • a hydraulic oil reservoir 32 Below the platform in its lowered position, space is provided for a hydraulic oil reservoir 32 and a fuel collector tank 33. Compressed air tanks 34 are located beneath the steps 31.
  • a hose reel 30 of the drum type which may be provided with a hydraulic rewind motor (not shown).
  • the platform 20 provides the support for the folding boom 24, the platform must remain in position while the fuel hoses are engaged with the aircraft.
  • the platform operating mechanism is therefore interlocked with the fuel supply so that the platform cannot be lowered during refuelling.
  • the drawbar 37 is preferably provided adjacent its free end with a control unit and handle coupled with the hydraulic motor drive so that the cart may be driven and steered by one operator, in its movement on the apron, for example, from one side of the aircraft to the other in refuelling.
  • the engine 19 is of sufficient power only to move the cart at approximately 10 - 15 mph (16 - 24 kph), and apart from its function in driving the hydraulics and the air compressor, is intended to provide motive power only for manoeuvring the cart in the region of the aircraft. Where it is necessary to transport the cart, for example for maintenance, it is towed by another vehicle, or moved by means of a trailer.
  • Figs. 5 - 7 components corresponding to those of the above-described cart are similarly numbered, and not further described, although it will be observed that components are rearranged to allow for the location of the refuelling boom.
  • the refuelling boom 126, 128 is raised and lowered by the platform, but when refuelling, will stay in the up position while the platform can be lowered and raised independently of the boom. After the refuelling has stopped and all the refuelling nozzles have been stowed, the boom can be lowered with the platform.
  • the boom is mounted with its pipes aligned parallel to the longitudinal axis of the cart, and includes a lower, common pipe 126 coupled by means of pivoting couplings 127 to a pair of upper boom pipes 128.
  • the lower pipe 126 is fed from the meter 118 (which, like the hose reel 130, is now moved to the side of the cart remote from the boom assembly) by means of lateral piping 129, and to allow for this the engine and compressor unit 119 is moved to underlie the boom assembly in its folded position as shown in Fig. 6.
  • Fuel hoses are provided in connection with the respective ends of the upper boom pipes 128. These hoses and the accompanying hose connectors will normally rest on the platform 20 and the hydraulic drive for the boom pipes will be derived from the engine and pump 119.
  • the hydrant cart of the present invention is believed to satisfy the varied requirements of major airport refuelling.
  • the cart is capable of relatively inexpensive manufacture and thus may be purchased in the numbers required for an airline to have a cart at each of its bays at the terminal, while providing the wing height range and manoeuvrability necessary if the cart is to be capable of servicing all the aircraft which may use the bay at which it is stationed.
  • the platform when fully raised will be stable with 90 mph (145 kph) wind load or jet blast without the addition of ground support stabilisers and will remain stable in accordance with the statutory requirements for ground support equipment.
